Hi all, Here are some preliminary images obtained on tonight's session, unfortunately interrupted by a thick marine fog. Anyway, seeing was favourable on some occasions and the SSTC WOS (also GRS and BA) longitudes were well placed for observation. The "f" pair of the SSTC wos is still very close (closer??; tonight about 6deg center to center in my rough evaluation; on Mar16 my pick was 6.5 deg, corrected by Hans-Joerg to 5.9 +/- 0.3 degrees). There is still a thin region of dark material between the two ovals, but with the spatial resolution that I have been able to reach with my setup and seeing conditions, it now appears to be vestigial (the small spot that has appeared some time ago betwen these two ovals looks smaller and hard to see). As in Mar16 images, the "p" oval of the pair is slightly N of the "f" oval. I'm very anxious to see more images of these... (my next favourable window is in two days, weather allowing it; I hope that many of you manage to get new data during this period!) The CH4 image continues to show the described appearence for GRS and BA, and shoes a faint positivity at the SSTC wos. It looks elongated, but there is not sufficient S/N ratio to get a clear discrimination between two closely placed spots. CH4 also shows a mid SEB spot in the disturbance "f" the GRS. Color and clear images show more elongated and thinner SEBn "feature" (when compared with previous days). NEB rifts also continue to evolve. Good observations Antonio ≪アントニオ シダダオ ポルトガル≫
